Norman Fitzroy Maclean (December 23, 1902 – August 2, 1990) was an American professor at the University of Chicago who, following his retirement, became a major figure in American literature.

Maclean is best known for his Hemingwayesque writing, particularly his collection of novellas A River Runs Through It and Other Stories (1976), and the creative nonfiction book Young Men and Fire (1992).

Born in Clarinda, Iowa, Maclean was the son of Clara Davidson and the Rev. John Maclean, a Scottish Presbyterian minister. His family moved to Missoula, Montana in 1909, which became a significant influence on his writings. These experiences are reflected in the short story The Woods, Books, and Truant Officers (1977), and the semi-autobiographical novella A River Runs Through It (1976).

Too young to enlist in the military during World War I, Maclean worked various jobs before embarking on a distinguished academic career.
